摘　　要：层序地层学是 1 977年由美国Rice大学的Vail教授及其Exxon公司的同行们在地震地层学基础上发展起来的。从 2 0世纪 80末期 ,国内外开始掀起层序地层学研究热潮 ,它在石油勘探中具有相当的实用性。在前人划分的基础上 ,把塔里木盆地台盆区志留系地层划分为 6个层序。在所划分的这些层序中第一层序为Ⅰ型层序 ,其余层序为Ⅱ型层序。第一层序由低位体系域、海侵和高位体系域三部分组成 ,而其余The theory of stratigraphic sequence is based on the development of seismic stratigraphy by Professor P. R. Vail of Rice University and his colleagues in Exxon Company. Due t o its benefit in oil exploration, many oil workers in the world have started,to study and apply the theory from late 80, 2000. The Silurian sedimentary formatio n of Platform in Tarim Basin is divided into six sequences. The type of the firs t sequence is .Ⅰ while that of the other five is Ⅱ.There are lowstand water system tract, transgrassive system tract and highstand system tract in the first sequence while there are only transgrassive syetem tra ct and highstand system tract in the othe r five sequences.
